Ordinary G33 is more suitable.
Probably so Andy, then back to the "driveline" for x before retraction, which would be a little easier of the tool, But shouldn't it also have a starting point z increment to simulate the Q of a g76? Thread wall is 15 degrees, and we sure don't want to pinch the tool by cutting on both leading and trailing faces. Its a very small advance but eases the force of the tool enough to not pinch it in the "kerf" and break it. So I'd set up an even loop by dividing the [end cut from the start cut] / 15 or perhaps a little more, then setup a z offset to be added per x increment, which ack my calculator would be obtained by a sin[15]*#<_x_inc>] call it #<_z_inc> and make z a tmp and adjusting that after the x inc is done. I would advance the start, and reduce the end z by the same amount, attaining a fixed z stop point. Sure seems like it should get the job done. OTOH my coffee hasn't really kicked in yet...
